What condition may result in abdominal distension in a pediatric patient?

Abdominal distension in a pediatric patient can be associated with a variety of conditions, but it is most commonly linked to gastrointestinal issues. In the context of drowning emergencies, while abdominal distension is not a direct result of drowning itself, it can occur due to secondary effects. For example, in cases of near drowning, if water enters the gastrointestinal tract, this can lead to bloating and distension. Furthermore, drowning can cause symptoms related to aspiration and fluid imbalance, which can also contribute to gastrointestinal symptoms.

Dehydration typically presents with dry mucous membranes, decreased urine output, and potential lethargy, without directly causing abdominal distension. An asthma attack, on the other hand, primarily affects respiratory function and would not generally lead to significant abdominal distension. Similarly, though an allergic reaction may result in swelling and other systemic symptoms, it doesn't specifically involve the abdominal cavity in a way that would cause distension.
